Nothing, anything? I don't actively plan for vacation except maybe where I'm gonna be. Once there, even if I am in another city, I go with the mood of the time and try not to feel obligated to do anything. If I stay home sometimes I end up doing things that were put off for a long time, I finish them, grab a beer meanwhile, afterwards, even if it's in the morning as long as it's hot and that's it for the day.
